Hi Everyone,

I plan to build an electric powered aircraft from scratch together with the help of some friends.
The aircraft must be able to carry a payload consisting of 6"x6"x6" box weighing approximately 3lbs and also a softball.
The aircraft is not required to exhibit any aerobatic capabilities and must have a wingspan no greater than 6.5 feet.

Any advice on where and how I can start sizing the aircraft regarding how big a wing area, tail volume, fin volume, control surfaces sizes, engine size, airframe mass, airfoil type etc.

I wish to build a database of similar sized models.

Any help appreciated
Kifi.
